I've seen some limited discussion on it.....Wasn't sure if anyone here has tried it or could tell me what kind of use it could be good for.

Dear Rob, I stumbled upon this schematic and I’m wondering if you could provide component values to it.Looking at thos thread remonded me of attached diagram for a single ended vari mu that I got from some obscure radio/electronics magazine about 20 years ago. It's got a weird cross coupling thing around to the 2 6BA6 that I never really got my head round, but I think it maybe cancels out the sidechain. Maybe someone with more experience can describe what's happening better. I never got round to building it to see what it's like.
Sorry that seems to be all the info I have on it.Dear Rob, I stumbled upon this schematic and I’m wondering if you could provide component values to it.
Seems like a quite interesting build.
The output stage is the interesting part, supposedly it can cancel the control-voltage feedthrough inherent in most single-ended compressors. Shouldn't be too hard to breadboard just the output stage with 'typical' values for anode and cathode resistors, and bench supplies for HT and CV. Rk2 will be for trimming the CV cancellation -try a 10k trimmer. If this stage can be made to work it wouldn't be hard to reverse engineer the sidechain. Here it is re-drawn for clarity.Dear Rob, I stumbled upon this schematic and I’m wondering if you could provide component values to it.
